Sun Microsystems VIRTUALBOX 3.0.0 - Manual (Page 31)

3 Starting out with VirtualBox
As already mentioned in chapter 1.1 , Virtualization basics , page 9 , VirtualBox allows
you to run each of your guest operating systems on its own virtual computer system,
which is called a “virtual machine” (VM). The guest system will run in its VM as if it
were installed on a real computer, according to the VM settings you have specified. All
software running on the guest system does so as it would on a real machine.
You have considerable latitude in deciding what virtual hardware will be provided to
the guest. The virtual hardware can be used for communicating with the host system
or with other guests. For instance, if you provide VirtualBox with the image of a CD-
ROM in an ISO file, VirtualBox can present this image to a guest system as if it were
a physical CD-ROM. Similarly, you can give a guest system access to the real network
via its virtual network card, and, if you choose, give the host system, other guests, or
computers on the Internet access to the guest system.
VirtualBox comes with many advanced interfaces, which will be described later in
this manual:
• chapter 7.3 , VBoxSDL, the simplified VM displayer , page 92 explains how to run
a single VM at a time with a reduced graphical interface;
• chapter 7.4.1 , VBoxHeadless, the VRDP-only server , page 94 shows how to run
virtual machines remotely;
• chapter 8 , VBoxManage reference , page 100 explains how to create, configure,
and control virtual machines completely from the command line.
The following introductory sections, however, describe VirtualBox, the graphical
user interface, which is the simplest way to get started.
3.1 Starting the graphical user interface
Depending on your host operating system, you can start VirtualBox as follows:
• On a Windows host, in the standard “Programs” menu, click on the item in the
“VirtualBox” group.
• On a Mac OS X host, in the Finder, double-click on the “VirtualBox” item in the
“Applications” folder. (You may want to drag this item onto your Dock.)
• On a Linux or Solaris host, depending on your desktop environment, a
“VirtualBox” item may have been placed in either the “System” or “System Tools”
